Using setString() to insert anything else from text types is not
possible any more using pgjdbc 8.0 jars, as the new driver makes
stricter use of type checking. One of our third-party apps also suffers
from this problems.
I can three solutions / workarounds for your problem:
- Use the pgjdbc 7.4 jar file, it should work fine against a postgresql
8.0 server. You can also stay with the 7.3 jar you used against your
7.3.3 server, as AFAIK pg8.0 still supports the V2 query protocol.
- Use a "?::numeric" cast in your prepared statement (not tested here).
- Update your application to use the proper numeric types.
